## Event Sequencer

### Overview

In many investigations, evidence is not found in the order that it was created during the incident. The notes feature in Autopsy allows one to make notes about certain files, but it does not help one to put a series of events in order.

The Event Sequencer allows the investigator to make notes and comments about pieces of evidence. Each note must have a time associated with it. For files and meta data, the times can be one or more of the MAC times. Other notes can have times entered manually. The sequencer will sort the events after each is entered so that the investigator can quickly identify where there are gaps in the findings.

### Adding an Event

To add an event for a file, directory, or meta data structure, select the Add Note button. At the bottom will be check boxes that allow an event to be generated for each of the file's times. The "standard" note does not have to be generated if it is not needed.

To add an event from a different source, go to the Event Sequencer from the Host Gallery (where the images are listed). At the bottom of the window will be an area where the new event can be added. The Source of the event will be shown where the file name of a file event is normally shown. Examples of this type include entries from firewall logs or reports from the help desk.

### Viewing the Sequence Events

The Event Sequencer button can be found in the Host Gallery. This window shows the events that are sorted by the time. Events that correspond to a file, directory, or meta data structure will have either [M-Time], [A-Time], or [C-Time] in the note that shows what time this event was generated from. Clicking on the name will show the contents of the file or directory.
